1.Retest the system.
(1) Change the power supply mode of the electric motor switch to OFF.
(2) Connect the M.U.T.-IIISE to the data link connector.
(3) Perform quick charging, check whether the trouble symptom persist, and check the DTC is set.
Does the trouble symptom persist?
Troubleshoot the set DTCs (Refer to DIAGNOSTIC TROUBLE CODE CHART) .
The trouble can be an intermittent malfunction (Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
